PHILIPPINE URTICACEAE. 19

Bontoc, Bauco, Vanoverhergh 1010. The leaves of the two last are less coriaceous 
than the type, so that this may not be a valid ditlerentiating character, otherwise, 
they are as described above. 
This species has hitherto been identified as D. lonyifolia (Burm.) Wcdd., but 
on comparison witli material of that species from Sikkim. Craib 575, 594, ai^d 
of D. edtilis Wedd. from China, Henry 10536, 12378 A, it seems much more distinct 
from either than they are from one another, and of the two slightly nearer Z). 
edulis. It differs distinctly from both in the coriaceous narrower leaves, and 
further from D. longifolia by its smaller glomeriiles nnd less-branched inflorescence. 
The pistillate perianth of Dehreycasia is always described as adnate to the 
ovary: not only in the Philippine species but in tlie Asiatic it seems to be easily 
separable, whereas in fruit the achene has hardly increased in size and is very 
loosely inclosed. The structure of the flowers of the Philippine and Asiatic 
material is identical. 
Dehregeasia is one of the names taken up by Weddell from Gaudichaud: in 
the Hot. Voy. Bonite, there is merely a plate, the explanations not appearing till 
186C, the genus therefore dating from AVoddell's monograph, ISo". There is an un- 
doubted older name, Morocarpus " Sieb. & Zucc, 1846: it is not used iiere, because 
there is an older Morocarpus.'^ The latter is regarded as a synonym of the still 
older Chenopodium Linn., and according to the Vienna Code, should be taken up 
for the genus. Leucocnide iliq.,^* 18ol, is generally cited as another synonym, 
but it is a mixture of two genera, the first two species being Leucosyhe: it is here 
held to be typified by the species now known as Lettcosyke mpiteU^tfa.

The species was originally collected by N^, both in the Marianne Islands and in 
Mindanao, and was described by Weddell, with doubt expressed as to its generic 
position, on accoimt of the absence of pistillate inflorescence. This but not the 
staminate is present on the more recent Mindanao material, and the remarkable 
nature of the inflorescence led to its too hasty publication as new, doubt being
